Database Error! HELP!!

Hello GAF users, We have suddenly a big issue with our dolphin and phpbb script. We were installing a Flashchat, on a seperate dictionary and database, and after we completed the installation, we are unable to access our 2 sites , running on dolphin and phpbb. We tried, deleting the database and the folder (through ftp), but it did not help. I have attached both screenshots (dolphin And phpbb) This is very urgent, so bid only if you can help us immediately. Payment, after fixing the issue - no escrow. Thank you in advance
